Hello and welcome to our very own and customized solar cells best in test!
Since ancient times, man has been looking for ways to extract energy from nature. The first and most elementary variant, which is also the one that has historically been used by far the longest, is of course the fire. Lighting fire and burning wood releases energy in the form of heat and light – two of the most important things we are looking for when we extract energy.
In the days of cavemen, the fire was used to cook food, shed light for practical reasons and also to keep warm – and not least to scare off dangerous predators who could lurk out in the shadows.
And if we look at what we use energy for today, there is actually not much that has actually changed. Our primary uses for energy are heat, electricity for lamps and the ability to cook. Since the time of the cavemen, there has been an enormous amount of so-called luxury consumption since the time of the cavemen, and there is no denying that a lot of our energy is consumed to watch TV, charge mobile phones and surf the internet. But the basic principle is still the same.
Ways to extract energy
Yes, a lot has happened since those old cavemen gathered around the fire and grilled freshly skinned rabbits on a spinning stick, and although the primary uses are still reminiscent of each other, there is one thing that has certainly changed. since then: the amount of energy we consume.
Since the discovery of electricity, humans have struggled to find ways to extract energy from nature, and in fact many of the methods are developing to a large extent, and are constantly getting better and better.
And as our energy needs have grown, the pressure on the energy industry has increased. We have realised that our planet cannot cope with just any strain, so a great awareness of the way we choose to extract energy has come to light in recent years. However, the primary sources of energy are still the same as they have been for a very long time.
The method of energy recovery that produces by far the most energy in the world today is still nuclear power. Put simply, nuclear power is an extremely efficient way of boiling water. A huge water tank produces a nuclear reaction that exudes immense amounts of energy, causing the water to boil, driving a turbine that then sends the energy on to convert into electricity.
The disadvantage of this method of extracting energy, which is under constant debate and discussion, is that it leaves behind radioactive so-called nuclear waste. This waste is not really known where to make of, and so far no satisfactory solution has been found where it is certain that it will not cause any problems in the future.
The risk is that containers will be torn apart over time and that radioactive waste will enter the groundwater, in case it chooses to bury it. Russia and Fukushima in Japan – the latter only a few years ago. It is simply not a completely safe method, which is why it is often criticised, especially from environmentally friendly sources.
One method that is even worse for environmental impact than nuclear power is coal burning. This method extracts heat energy by simply burning coal. There is an almost infinite asset and it is easy to administer. The problem, however, is that it has been shown to work extremely the ozone layer, and that it is one of the biggest culprits and contributors to the greenhouse effect.
Hydropower is currently the most efficient and safest method of extracting energy, although in recent years it has been competitive from solar power. Our Swedish energy comes largely from hydroelectric plants built adjacent to our rapids, rivers and rivers. Here, the major problem is that the method is associated with major limitations.
There is a limit to how much can be expanded a river with hydroelectric power stations, and when it is reached, the capacity to extract energy from said river is also reached. With an energy consumption that is constantly increasing, one simply needs a more efficient method of extracting electricity.
Like solar power, wind power has developed tremendously in recent years, but there is still a long way to go here, and there are major limitations. Wind turbines are big, sound a lot and no one really wants to live near them.
Nor do they produce anywhere near as much electricity as we need. Wind power is a welcome addition, but nothing that we will manage – neither now nor in the future.
Yes, and we have the greatest promise of the future when it comes to methods for extracting energy – solar energy. By harnessing the already existing energy that constantly flows from the sun in our solar system, it is possible to extract quantities and re-quantities of energy.
For many years, there were doubts from numerous authorities and interest groups, who argued that solar energy was nowhere near effective enough to remedy the impending energy crisis. However, these critics have had to revise their statements in recent years – they should at least do so in cases where they have not.
Solar energy has evolved tremendously over the past decade. To take advantage of the sun’s energy, we use so-called solar panels (more about exactly what a solar panel is just about), and with each passing year, the solar panels become cheaper, better and more efficient. It is not uncommon at present for people to choose to rig up solar panels on the roofs of their houses, thus providing some or all of their own energy supply.
And as long as we live, the sun will shine on us – so why not take the opportunity to put yourself on the cutting edge of energy development, and install your very own solar panels?
The use of solar panels is, of course, a phenomenon that is extremely dependent on climate. It is, of course, a much more effective method in, for example, South America or the southern United States or Asia, where the sun shines much brighter, and where it does it all year round.
But that is not to say that it makes no sense to use solar panels in Sweden – no, far from it. The more sun, the more energy – but even in Sweden we have many long hours of sunshine every year, and all the energy that you do not extract from the sun’s warming rays, is energy that simply goes to waste. It’s that simple.
Now, before we plunge head in handin our solar cells best in test, let’s take a closer look at what a solar panel actually is for a magical invention, and how it works.
What are solar cells, and what is a solar panel?
A solar panel is simply expressing a plate that, when exposed to the sun’s rays, converts solar energy into electricity. So how is a panel like this assembled? Yes, there are a few different variants, and the ways to build solar panels are constantly evolving.
This is clearly an industry that is in its cradle. At present, however, the design of the vast majority of solar panels can be summed up as follows: at the bottom of the panel there is a base plate. On top of it is a layer of aluminum foil, on top of it lies the solar cells themselves (which in the vast majority of cases consist of silicon), on top of these lies a plastic film and on top of it a layer of glass. In fact, it’s not more complicated than that.
These panels then come in different sizes, in different designs and of different qualities. Depending on price and quality, they have the ability to take advantage of different amount of energy, and can also be different fragile. The single most important parameter to keep track of when it comes to comparing different solar panels is a device usually referred to as WP.
WP means watt peak, and is a number that indicates how many watts the panel can produce in its full capacity. This is thus an indication of how much energy you can get out of your solar panel, and thus a figure that is very important to compare with size and price, if you want maximum currency for your investment in solar panels.
Solar cells best in test
So, to spread some clarity in this jungle of products, we have now put together our very own, tailored solar cells best in test, where we selected and tested three different models of solar panels. Come with me!
Polycrystalline Solar Panel Phaesun Sun Plus 5 5 Wp 12 V
This very budget-friendly solar panel from Phaesun is clearly an option that doesn’t wear much on your wallet – of course, depending on how much space you intend to fill with solar panels to begin with. Thick.
It has a deliciously wide silver frame, blue solar cells and is thus completely squarely designed – something that contributes to a stylish and elegant look. It is one of the cheapest solar panels on the market, and it weighs 0.9 kilos.
It produces electricity with a WP of five, which is among the lower figures for a single panel, but at the same time something of a standard measure for the slightly cheaper models. This is simply a basic but very affordable solar panel. The test group for our solar cells best in test is completely unanimous in recommending this model to anyone interested in using solar panels.
Polycrystalline Solar Panel Sunset F-Lite 10 Wp 15.5 V
Now it’s going to be more expensive. One step up in the price range we find this model from Sunset. Here we have a panel that is straight angular according to the dimensions 35 by 50 centimeters, but only three centimeters thick. Furthermore, it weighs only just over a kilo, and is thus good much lighter per square centimeter than the previous model.
Another good news is that it consists of two separate fields of solar cells, each of which can extract energy to a degree of five WP, and thus lands on a total of ten WP – twice as much as the previous model, even though it is not close to being twice as large. This is simply the most effective solar panel in our solar cell to date best in test and it is a unified test group that thinks it is a brilliant panel (in the true sense of the word) – albeit a little in the most expensive team.
Polycrystalline Solar Panel SunWare 20144 20 Wp 12 V
Well, then it was time for the absolute super-worst in this solar cell best in test. This is the model that makes the other variants seem almost meaningless, but it is also the model that makes the owner of the slightly thinner wallet to completely shake the shoes. This is an incredibly exclusive solar panel, and it is an extremely efficient one.
Let’s take a closer look at its attributes and properties. This, too, like the previous model in our best in test, is a rectangular solar cell. It measures 64 by 27 centimetres and is thus only slightly larger than the previous model in terms of total number of square centimetres, but at the same time it is even slightly narrower. And here’s more good news: it weighs only 1.2 kilos, only a fraction more than both previous models in our solar cells best in test.
So, the question that we know you can’t wait to get answered: how much electricity can this bad guy produce? yes, buckle up. Polycrystalline solar panel SunWare 20144 20 Wp 12 V produces electricity according to a capacity of no less than 20 WP – in only one solar field!
This panel is thus only slightly larger than the previous model in our best in test, but it produces electricity at a maximum of twice as high efficiency. This is simply a monster when it comes to solar power, and anyone who takes their solar panels really seriously is right to invest in this panel today.
And remember – one of the absolute biggest reasons to invest in solar panels and solar cells is the ability to save money in the long run. With this solar panel you will have the potential to save almost twice as much money as you would have compared to the previous model.
Almost all participants in the panel for our solar cells best in test think this is an extremely wise investment, and recommend that you take a slightly higher cost now to save money in the long run. After all, that is exactly what the extraction of solar energy is all about in the first part!
